Absorption and urinary excretion of procyanidin B2 [epicatechin-(4β-8)-epicatechin] in rats

Free Radical Biology and Medicine, 2002
We evaluated the bioavailability and plasma antioxidative activity after administration of procyanidin B2 [epicatechin-(4beta-8)-epicatechin] in rats. After procyanidin B2 administration, procyanidin B2 is absorbed and excreted in urine, and a portion of the PB2 is degraded to (-)-epicatechin and to the metabolized conjugated and/or methylated ...

Polymeric proanthocyanidins: interflavanoid linkage isomerism in (epicatechin-4)-(epicatechin-4)-catechin procyanidins

Journal of the Chemical Society, Chemical Communications, 1981
Heterogeneity of the interflavanoid linkages in trimeric procyanidinns was demonstrated by the isolation of epicatechin-4,8-epicatechin-4,8-catechin (1), epicatechin-4,8-epicatechin-4,6-catechin (2), and epicatechinditions used, thus establishing the validity of partial acid-catalysed thiolytic cleavage for deeteermining the configuration of ...

Epicatechin: Endothelial Function and Blood Pressure

Journal of Agricultural and Food Chemistry, 2012
Epidemiological studies indicate an inverse relationship between flavanol intake and the risk of cardiovascular disease. Potential mechanisms include their effects on endothelial function and hypertension. A number of studies have shown that flavanol-rich cocoa reduces blood pressure and endothelial dysfunction, whereas black tea may have opposite ...

Protective Effect of Epicatechin, Epicatechin Gallate, and Quercetin on Lipid Peroxidation in Phospholipid Bilayers

Archives of Biochemistry and Biophysics, 1994
Antioxidative effect of (-)-epicatechin,(-)-epicatechin gallate, and quercetin was examined by measuring the inhibition of lipid peroxidation in large unilamellar liposomes composed of egg yolk phosphatidylcholine (PC). These catechol-type flavonoids were stable in the liposomal suspension.

Structure, stability and antioxidant activity of dialdehyde starch grafted with epicatechin, epicatechin gallate, epigallocatechin and epigallocatechin gallate

Journal of the Science of Food and Agriculture, 2022
AbstractBACKGROUNDCatechins, a member of the flavonoids, exist widely in teas, and have health benefits. However, catechins have poor stability, which greatly limits their application. In order to improve the stability of catechins, different catechins including (−)‐epicatechin (EC), (−)‐epicatechin gallate (ECG), (−)‐epigallocatechin (EGC) and ...

Natural (−)-fisetinidol-(4,8)-(−)-epicatechin profisetinidins

Phytochemistry, 1990
Abstract The natural occurrence of the first profisetinidins associated with (−)-epicatechin is demonstrated in the heartwood of three legumes. 1 H NMR spectroscopy at 300 MHz permits assessment of the relative abundance of the predominant rotamers in each of the heptamethyl ether diacetates of the (−)-fisetinidol-(4α,8) and (4β,8)-(−)-epicatechins ...

ERYTHROCYTE SODIUM/HYDROGEN EXCHANGE INHIBITION BY (−) EPICATECHIN

Cell Biology International, 2001
Epicatechin, a flavonoid belonging to the group of compounds collectively called catechins, have been reported to possess insulin‐like properties. Besides their anti‐diabetic properties, catechins also show growth inhibition. Since cytosolic pH (pHi) plays a role in cell proliferation and the Na/H exchanger (NHE) is the major pH (pHi) regulatory ...

Epicatechin influences primary hemostasis, coagulation and fibrinolysis

Food & Function, 2019
Epicatechin leads to decreased platelet activity, displays an anticoagulant effect and induces a pro-fibrinolytic profile using global assays. These epicatechin-induced hemostasis modulations strengthen the interest of epicatechin for CVD prevention.

Influence of Gallate and Pyrogallol Moieties on the Intestinal Absorption of (−)‐Epicatechin and (−)‐Epicatechin Gallate

Journal of Food Science, 2012
Abstract:  The cellular accumulation of individual catechins was measured as an index of intestinal absorption to clarify the interactions among catechins. The cellular accumulation of (−)‐epicatechin (EC) increased in the presence of other catechins.

‘Leuco-cyanidin’ and Epicatechin

Nature, 1953
Bate-Smith and Swain1 have recently come to the conclusion that the so-called condensed, ‘catechin’, tannins are in many instances identical with the ‘leuco-anthocyanins’ described by Robinson and Robinson2. Recent work here has suggested that the catechins and ‘leuco-anthocyanins’ are extremely closely related.
